WARNING
EWJ00282

Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.

Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ00321

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.

Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and thefuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity of
sparks, open flames, or other sources of
ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 47 for seat removal
and installation procedures.)
(4) Pull the visor up, and then lift up the rear
of the hood.
Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.
(7) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it heats
up, heat from the engine or the sun can
cause fuel to spill out of the fuel tank. Donot leave the watercraft with a full tank in
direct sunlight.
(8) Wipe up any spilled fuel immediately with
a dry cloth.
(9) Securely install the fuel filler cap by tight-
ening it until it clicks.

A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely drain
the bilge water, remove the watercraft from
the water and drain the bilge water on land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
that collects in the engine compartment is
drawn in by the vacuum that is generated in
the jet pump and discharged from the water-
craft through the jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 min-
utes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the
engine compartment can splash into theengine, which can result in severe dam-
age.
